📍Key points of this local guide
→Local irradiation: 1260 kWh/m²/year, climate zone H1 (North). Hiver rigoureux mais étés chauds. L'ensoleillement est suffisant pour rentabiliser une installation, avec patience.
→A 3 kWp installation produces around 3,270 kWh/year in Strasbourg, which is ~469 €/year saved on your bill.
→Average payback period in Strasbourg: ~14 years. The self-consumption bonus has been abolished since June 2026.
→VAT can be 5.5% under 5 cumulative conditions (capacity ≤ 9 kWp, residential building, PPE2-V2 certification, compliant heavy metals content, active EMS, mandatory since January 2026). Without an EMS: 20% VAT. Ask about the Grand Est regional grants through your ADIL (the departmental housing information agency).
Sunshine in Strasbourg
Strasbourg is in climate zone H1 (North), with an annual irradiation of 1260 kWh/m²/year according to PVGIS data (European Commission, JRC). Hiver rigoureux mais étés chauds. L'ensoleillement est suffisant pour rentabiliser une installation, avec patience.
For a 3 kWp installation (6 to 8 panels), that means around 3,270 kWh of solar output per year, with a peak in June-July and a drop in December-January, typical of the zone.

⚠5.5% VAT, 5 mandatory cumulative conditions: capacity ≤ 9 kWp · residential building (regardless of its age) · PPE2-V2 certification (carbon footprint below 530 kg CO2/kWp, which can be checked on certisolis.com) · compliant heavy metals content · active EMS/SGE mandatory since 1 January 2026 (an energy management system able to control the equipment). If even one condition is missing: 20% VAT on the whole installation. Batteries are always at 20% (legal exclusion). The CRE bonus is paid in a single payment by EDF OA (the feed-in tariff operator) when the Enedis (grid operator) connection is made, and your RGE-certified installer (French quality label) takes care of it.
Profitability in Strasbourg: the full calculation
With 3,270 kWh/year produced and about 70% self-consumption (a household at home during the day or appliances scheduled for solar hours), here is how the savings break down for a household in Strasbourg:
Self-consumption (~70%)
~458,0 €/year
2,289 kWh × 0,2001 €/kWh
Surplus fed into the grid (~30%)
~10,8 €/year
981 kWh × 0,011 €/kWh (surplus buy-back tariff, June 2026 ministerial order (arrêté))
~469 €
estimated annual savings
~14 years
payback period
ℹThese figures assume an average profile: a tariff of 0,2001 €/kWh (1 August 2026), an annual increase of 3% and about 70% self-consumption. Actual profitability varies greatly with the orientation (due south is optimal), the roof tilt, the presence of shading and how much you are at home during the day. A household that is away during the day can see its payback period lengthen by 2 to 4 years compared with the estimates above. These tariff-increase assumptions are reasonable but uncertain; if tariffs stagnate, the payback period lengthens.

Grants available in Strasbourg (67)
In 2026, residents of Strasbourg can benefit from several grants that can be combined:
CRE self-consumption bonus: abolished since 1 June 2026 for all new installations.
5.5% reduced VAT: under 5 cumulative conditions: capacity ≤ 9 kWp, residential building (regardless of its age), PPE2-V2 certification (carbon footprint below 530 kg CO2/kWp), compliant heavy metals content, and active EMS/SGE mandatory since 1 January 2026. If a condition is missing: 20% VAT on the whole installation. Batteries are always at 20%. Check eligibility with your RGE installer.
MaPrimeRénov': does not cover photovoltaic panels that generate electricity. This scheme funds solar thermal (hot water), insulation, heat pumps and renewable heating, not PV.
Grand Est regional grants: some regions and local authorities offer additional support. Ask your ADIL or the local Espace Info Énergie (energy advice centre).
Dedicated financing: ask your bank about financing offers dedicated to renewable energy.

Frequently asked questions: Strasbourg
How much does a solar installation cost in Strasbourg ?

For 6 kWp, allow ~11,484 € gross. Prices vary with your roof and the installer: ask for at least 3 quotes from RGE installers.
What payback period can you expect in Strasbourg ?
With 1260 kWh/m²/year of sunshine and savings of around 469 €/year on a 3 kWp installation, the payback period is estimated at ~14 years. This payback period depends on your self-consumption rate, the tariff of your electricity contract and the orientation of your roof. Our simulator calculates your exact payback period with the real PVGIS data for Strasbourg.
What grants are available in Strasbourg in 2026?
The main grants in Strasbourg in 2026: VAT (the CRE self-consumption bonus has been abolished since 1 June 2026), 5.5% VAT under 5 mandatory cumulative conditions, including an active EMS/SGE since January 2026 (without an EMS: 20% VAT), and Grand Est regional grants through the ADIL or the Espace Info Énergie. Note that MaPrimeRénov' does not fund photovoltaic panels, only solar thermal, insulation and heat pumps. Ask your bank about financing offers dedicated to renewable energy.
What capacity should you install in Strasbourg ?
The usual rule is to aim for 1 kWp per 1,000 kWh of self-consumed annual consumption. In Strasbourg (1260 kWh/m²/year), 3 kWp produces ~3,270 kWh/year, which suits a household of 2-3 people using ~3,500 kWh/year. For a household of 4-5 people (6,000 kWh/year), aim for 6 kWp. Our simulator optimises the capacity for your exact profile.
